After years breathing AMD's dust, Intel beat its rival to the punch by releasing its quad-core Xeon 5300 'Clovertown' processor for servers in November. But AMD's 'Barcelona' quad-core chip, due to arrive midway through 2007, will be a significant notch faster than the Clovertown chips expected to be on the market at that time, said Randy Allen, AMD's corporate vice president for server and workstation products. "We expect across a wide variety of workloads for Barcelona to outperform Clovertown by 40 percent," Allen said.
